My Battery Usage indicates that the Home and Lock Screen are using 30% of the battery check how quickly it's set to autolock. shorten it to one minute for a week and see if that changes anything. if it's sitting at lock screen for a long time, it might as well just be dimmed and locked.

Please check this ultimate guide in regards to battery problems out. Also I think you should take a look into: Settings > Location settings (which apps are allowed to use it and when) Settings > E-mail > Check your e-mail fetch/push settings. Settings > Notification center (which apps are allowed to push notifications e.g. messages, badges, sounds..) It ...

I think iOS 8 will be the last ios the iphone 4s will support. Apple said that there will be more software updates before that should add better preformance and new functions to the system. The beta of iOS 8.2 made sure that the preformance on the iPhone 4s get a bit better. When your iphone is a couple of years old, you can consider buying a new iphone ...

I have the same problem. Max life is 12 hours and very very little use. It goes down by 5% per hour!!! Apple said battery fine and I should only expect 10 to 12 hrs. Back several iOS ago I could get well over 24 hours. Sounds like the want to force us to get new iPhones 6.

The problems were resolved by Apple servicing the hardware.

This hibernate/sleep thing has been driving me insane. And I agree that Apple should put more energy into fixing this pmset behavior. I will be clear. I love hibernate mode and it used to work perfectly in older models and OSs (just running sudo pmset hibernatemode 25 was enough). Now Apple broke something and this just doesn't work since Yosemite. I have ...

I remember asking the guy at the Apple store this very question back when I bought my black MacBook 13" back in 2007. From what he said and from what I've read over the years regarding battery health, most of what Apple have stated on the page you referenced is applicable to you. If I could offer some more advice, it would be this. Cycle your battery at ...

In general, it isn't a good idea to put a power adapter on a light dimmer as the circuitry could malfunction if the voltage is too low. That being said, I believe the 45W adapter for the MacBook Air will survive- it just won't charge if the dimmer reduces the voltage below 100 volts. The AC is converted into DC and then applied to a voltage regulator ...

I make no guarantees here. Probably no harm will come to the MBA. The power is buffered through the transformer in the power adapter. You might burn out your power adapter if you vary (dim) the voltage while it is in operation. I would also strongly suggest not plugging in the power supply to the adapter until you have adjusted the adapter to full ...

This worked for me on my macbook air 3,1: I went to system preferences/energysaver/clicked the battery tab and hit restore defaults. It started taking a charge after that. I had completely let the battery run out while watching cartoons and I think it caused it to go into some kind of safety mode.

I can not repair your battery, but try to provide you with information to decide if the battery is EOL. There are 3 conditions reported. Replace Soon: The battery is functioning normally but holds less charge than it did when it was new. Replace Now: The battery is functioning normally but holds significantly less charge than it did when it was ...

Only if the battery discharged to about 20% overnight for some reason it will count as new charge cycle. For example if unplug at 100% and plug back in at 80% it is not counted as new charge cycle.

the ipad has no battery to fully turn on, but it wants to, so when the battery is only like 1% it attempts to restart but it dies only while showing logo. You should try holding down at the same time home and turn off button each time you see logo, multiple times like 40 times, to accumulate enough power. Then let it turn on. when you see home screen with 2% ...

don't use a third party cable or plug when charging your iPhone, they can damage your iPhone, causing them to overheat.

Mine did the same thing. I wiped and restored it to a backup several times with no improvement. The Genius at The Apple Store couldn't figure out what was wrong and eventually replaced it. The new one does the same thing, but not with as much frequency and it doesn't randomly restart itself with the apple screen as the old one did. My original 5s always ...

Happened to me but different iPhone model. I got hints from here https://discussions.apple.com/thread/4338574?start=0 Starting from fresh (factory reset) worked for me.

There’s no need to let it discharge 100% before recharging. Apple lithium-ion batteries work in charge cycles. You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery’s capacity one day, then recharge it fully ...

Yes, the ideal time to charge your phone is around 50% depletion. Ars Technica explains why: Full discharges put a lot of strain on the battery, and it's much better practice to do shallow discharges to no lower than 20 percent. In a way, this is like people running for exercise— running a few miles a day is fine, but running a marathon every day is ...

If you are truly dual booting (using Boot Camp) you will find your battery life better on OS X than on Windows. However, when you boot into OS X, you won't suffer any ill effects from having a separate Windows partition sitting idle. If you opt to run Windows in a Virtual Machine (using, for example, Parallels Desktop, VMWare Fusion, or Virtualbox), you ...

You have to consider the time of your iphone, I mean if its a 2010 factory made iphone the reason its obvious, otherwise you have to go to an Apple Service Retail/Shop and ask for a revision cause thats not normal.

It might not help the OP, but Apple has battery replacement program for iPhone 5. You can check eligibility on Apple site Apple has determined that a very small percentage of iPhone 5 devices may suddenly experience shorter battery life or need to be charged more frequently. The affected iPhone 5 devices were sold between September 2012 and January 2013 ...

Did you bring it into a Apple store? If you did and asked I'm sure they would do it. If you sent it in, they don't have to do it, but maybe if you get a lucky the technician will do it.

When an iPhone is plugged in, it will boot up (that is actually a common techniques used for restarting an iPhone if the power button doesn't work for some reason). If the iPhone is powered off while charging, it will remain powered off and will not automatically come back on. I understand that you have an iPhone 4 and there is the chance that it was ...
